The tumble generator valve (TGV) is a device installed on most modern Subarus for emissions purposes. The purpose is to more effectively mix air and fuel during cold-start operations. The issue is that even when the valves are wide open, during warm operation, they still create an unnecessary restriction - less than ideal for those chasing high power figures. 

Blox Racing solves this problem with a bolt-on solution that doesn’t require irreversible modifications to the TGV system. This means that if the factory emissions systems are needed, the user could easily return them to stock. When the TGV delete kit is installed, users can enjoy the unrestricted potential of their FA20DIT. 

Delete Kits are precision CNC-machined from billet aluminum to ensure a leak-free fit on the gasket surfaces. Features an anodized finish for durability. 

A retune is required to take full advantage of the TGV deletes.
